Fitness exercise device for strength training equipment

Abstract

This invention provides a flexible fitness device for strength training, particularly a flexible fitness device capable of training two or more different muscle groups. It includes a control instrument through which the user can access a shared control unit. This shared control unit includes a resistance adjustment module, a transmission module, and a displacement adjustment module. The transmission mechanism of the transmission module is physically connected to the resistance mechanism of the resistance adjustment module. The displacement adjustment module changes the position of its transmission mechanism. The bidirectional motor of the resistance mechanism forms a single axis within the main body and applies resistance to the transmission mechanism of the aforementioned transmission module. This allows the transmission module to have at least two or more movement modes, enabling the training of at least two or more different muscle groups.
